Cool deal. I always like to see animal studies. The girl's face on the first page looks a little off, the jaw line is over way too far. I tend to do that sometimes, too. Other than that I think you've got some fun ideas going on here.

Looking good so far, theres some good control of line and form, the animals are looking good, they are a difficult area to do, especially horses, but yours are looking good. Keep up the good work ya sausage.

great stuff. But like Saikin said i wanna see more. You have a great handle on your lines and anatomy of animals and things. What about forshortening. lets see some wild images of rearing horses and leaping jaguars or a person flying right at you or something.

Awesome work on the cougar (or lion, or whatever it was), and I loved the shading and detail on the horse's head. Always good to see good animal pictures, keep up the good work.

Some criticism on the "antelopes":

-The face on the left one is a bit too round (looks like shes puffing or holding her breath or something)
-The ear is a little too high up, but not noticeably.
-The back horn would be coming out of the back of her head.
-I believe someone already mentioned the differences in eye sizes?

Besides those very small things, the pictures are great. Would be a lot better with some shading or texture thrown in; color optional.

Some face sketches. A quick 2 minute ballpoint pen of my housemate who plays a lot computer games next to my pc, so I get the profile view of her quite a bit :

Two more sketches. The top one is also from life but I messed up horribly. (yes video games for profile models lol) I didn't pay attention and ended up drawing it from 2 perspectives. The chin, mouth, nose and ear are profile. The rest of it is from a slightly lower view angle. ARGH!! Thought I'd post it up anyway. The second is a head from a photo ref.

Some hand studies from photo reference. They're all from "Bodywatching - A field Guide to the Human Species" by Desmond Morris. Old book but pretty good reading with lots of interesting photos of the human body. I'm regretting picking the photo of the Indian woman's dancing hand because her fingers were angled scarily.
